I'm struggling to remember what to do to work out waters of crystallization.
You essentially do a series of calculations to get the Mr of the compound. You find out the Mr of the anhydrous salt and then take that away from the total and divide what you get by 18 to see how many moles of water are bound to each molecule.

Oh okay, thank you haha, but I thought you divide it by 18? Because O=16 and H2=2 ?

Cheers for that mate haha, helped me much faster than finding this on the internet somewhere
Nowt wrong with btec science, it better prepares you for industry in a lab and it's not assessed via a memory test
Mate tbh, i don't even care if I move down to Btec anymore, I'm sick of A levels and everything to do with them and it's only been a month like omg pls just kill me. Literally A level Physics is the easiest of my A level in my opinion haha

Do the btec if A level is making you feel that bad. Seriously.
ah gotcha. Could you just drop chemistry? Depends what you want to do at uni etc
I think I want to do Bio-chemistry or Astro physics, so I don't really want to drop it... but I don't even know if they can put me into a btec now because I think the time to change course is over now but I'm on a contract where if I do bad then I get moved into a btec so I don't even know what will happen if I fail my resit.

definitely worth talking to someone at your college to clarify what your options are. *
